3M™ Four-Wall Header 3000 Series Datasheet

Category: 3M, Connectors, Electronics

Overview

The 3M Electronic Materials Solutions Division provides details about the 3M™ Four-Wall Header 3000 Series in this datasheet. It highlights features such as the latch/ejector mechanism, straight and right-angle configurations, and high-temperature insulators suitable for no-lead soldering processes, along with its compliance with Restriction of Hazardous Substances (RoHS).

Physical and Electrical Characteristics

The header is constructed with a glass-filled polyester (PCT) insulator and features a UL94V-0 flammability rating. Contact material is a copper alloy with an underplating of nickel and gold over the primary contact area, and a tin-lead or matte tin solder tail. It also includes a 3M logo and part identification marks.

From an electrical perspective, the header offers varying current ratings depending on the number of powered contacts, with a maximum of 5.00A for a single contact to 1.75A when all contacts are powered. The insulation resistance is over 1×10⁹ ohms, and it withstands voltages up to 1000Vrms at sea level. The headers have a UL current rating of 10A and a UL voltage rating of 125V.

Environmental Tolerance

The datasheet specifies a temperature range from -55°C to 105°C, a processing temperature rating of 260°C for single pass soldering, taking into account the moisture sensitivity level as per J-STD-020.

Ordering Information

Headers can be customized based on various platings, such as standard temp (matte tin tails), high temp, and flash gold tail options. Specific part numbers and configurations are dependent on pin count and contact tail dimensions, with detailed information provided on how to order depending on tail type – straight, right-angle, wire wrap, or kinked versions.

Mounting and Polarization

The mounting dimensions and instructions are included, accompanied by information on the use of polarizing keys and centerbump polarization to ensure correct orientation during board mounting. The headers are suitable for reflow soldering using paste in hole techniques, and they come with optional polarizing posts for greater stability.

Details of Availability

Headers can be obtained with or without center notch polarizing fins. The datasheet encourages contact with 3M’s technical sales team for additional information and availability.

Regulatory Compliance

For regulatory information, users are directed to the appropriate section on the 3M Connectors website.

Additional Notes

The datasheet also provides details on latch/ejector systems and the absence of latch/ejectors, indicating different types of latches that can be used with the headers. The revision history is included, citing dates and reference numbers for significant changes made to the datasheet.
